An object of one form of this invention is to provide a spacer that will be more rigid when set in place than spacers heretofore provided for this purpose. I

The invention broadly includes two pieces of wire, one of which is adapted to form a standard and is provided with a sharpened point adapted to bedriven into the form member,

V i and the other of whichhas the 'sidethereof adj acent to said point, spaced from the other end of'the standard the distance required to be provided between the form and the structural metal to be encased. The invention comprises a spacer standard having a point adapted to be driven into the form member and having an intermediate head'or cross bar fixed to the standard to serve as a stop for spacing the top or'driving end of the standard from the form into which the point of the standard is to be driven. 'This form of spacer isespecially adapted for rapid ,and cheap manufacture and also for being. readily handled by the workmen setting them in place; and' such spacer is adapted to cheap and simple manufacture with straight standard or a loop standard; either of which may be made by laying the" standards in a row side by side spaced apart 7 40 according to the lengthof the ?stop that is to be applied thereto, and applying a straight g wire to the entire row and welding the wire i and thestandards together and then cutting the cross-wire into lengths, the ends of which are 'equidistant from the aXes of theirstandards respectively, and the operation of applying' and welding the stop bars to the standards may be varied, according 'to the convenience or operativemeans of ,the manu- P faoturer. e u i The standards and "stop bars may be i formed outof straight wire, and in some' instances the standards may be made'oii'a U or V-shaped bend of such wire; the cross bars in the latter case being welded to both y legs of their standards respectively, at" the appropriate distance from the point or points, as the case may be, of 'the standards. i

The length of the standardsfrom, point to stop bar and from the stop sides or edges 69 of the stop barsto the drving'end's or"heads of the standards,' respectively 'will be deteri mined by the purpose forwhich 'the' spacer is intended; andthe completed spacerslmay be used for varous purposes n addition to what is above specified, as for instance,` for spacing wire mesh from forms against which walls may bebuilt by cement shot from' a cement gun. i r

The inventionis broadly new, basic and 70 particular in a form which comprises an A- shaped staple; and said'staple is made of tw o pieces of; wire, onehaving sharpened ends and the other being a cross bar connecting the limbs of the loop near the sharpened ends 7 to form a stop for the staple when the 'same i is driven into a plani( or Other object; a stop face of the bar being spaced from the outer 'face of the bend a 'distance equal to the i space required betweenthe form and structural steel'or iron or' other object -to be en-' 'cased by the cement or concrete material.

The accompanyin'g drawing illustratesthe invention. i i g I Figurel is-a face view of my newly invented formspacer, i 0 Fg a is'an edge View;

' Fig.- 6 isa vertical section of an I beam and 'form for' a soflit with' spacers in place;

' The -sha'pe body lforming the' standard- I a i i io of the spacer and the stop bar 2, of the spacer as shown in Figs. 1, 2, 3, 4, 5 and 6, are preferably made of pieces of polshed steel wire of appropriate' gage and of requiste lengths, as for example, when the space between the form and a steel I-bean or other structural iron is to be two inches, the V body i on standard l, may be` of No. p'olished steel wire approximately si:: inches long bent to V form; and thestop bar may be approXimate one inch long.

The ends of the standard or body wire, will be cut aslant as indicated at & and the ends of the stop bar or wire may be practically square across as indicated at 4 in Figs. 1, 2 and 3.

The wire for the body or standard 1 will i be bent midway between its ends to form a j rounded driving head 5' and the stop bar 2 will bewelded to the divergent limbs with the` ends of the stop bar nearly fiush with the outer edges of the limbs and arranged with and the standard afiord ready gra'sp for the i hand; 'and when the staple is driven the cross Construction shown nor to the use of round wre; ;as'other construction and wre of other cross sections may be used where convenient or desired;'nor do I limit myself to the particular shape of the bend at the head 5, nor to the particular cut of the points 3.

The'stop bar 2 is secured to the standard by aweld 9 at each of the contacts between the bar and standard in all of A the forms shown. v i

In practical manufacture the form shown in Figs. 1-4 may be readilymade by first clipping the wires for the V-bend aslant in any desired way or form and then bending such wire into the V or U-shape seen most clearly in Fig. 1; laying a desired number of the' V or U-shaped standards thus formed, side by side with their longitudinal aXesin parallelism with each other, then laying a straight wire across the limbs of all of the loops, then i electrically spot weldin'g by suitable spot welding process, the cross wire, to the sevauxiliarymeans for supporting the staple on the form member.

The ends of the limbs may be clipped ofl for a finished job or bent over for plaster finish.

The junction of the stop bar and standard afiord an easy hold for the fingers.

In practice the mechanic using either form of standard shown, will adjust the point to the proper place on thewooden form and will by the strokeof a hammer upon the driving head 5 set the standard inthe wooden form until the stop comes against such form, thus gaging the space between the surface of the form and the surface of the metallic structural element? that the form is to be spaced from and then the parts of the form will be brought into position to close the structural element and then the concrete may be poured in theusual way as will be understood by the diagramnatic showing in Figs.

5 and 6.,

I claim In the art of concrete fireproofing for steel structures, a spacer for maintaining a predetermined distance between the side of a metallic structural element and a member of a wooden form to confine the concrete, said spacer consstng n a staple formng a standard pointed' at one end forinsertion into the eral limbs as at 9 and then clipping off the wire between the standards. r

In setting the spacers to be driven into th form member, the 'junction of the cross bar bar prevents the legs of the staple from: spreading and insures that the standard will f maintain its proper form so asto insure that' the spacng will be'correct. When the staple 1 is driven into the form member, the cross bar V is ;disposed fiush'againstthe surface thereof;

functioning as a stop, and likewise forms an
